Solvent P-5: features and benefits

When working with paints and varnishes, solvents are indispensable. They are necessary to change the structure of a varnish or paint. The composition lowers the viscosity of the dye and reacts with other binders. This is the main purpose of solvents. Also, the substance is used for cleaning surfaces and degreasing.

In this article, we will tell you more about the popular P-5 product.

P-5 is an organic compound used when working with paints. With its help, it is easy to achieve the required consistency of the dye. The material will come in handy in order to put in order equipment and painting tools. Excellent technical characteristics and properties played an important role in the development of the product's popularity.

The solution is used by ordinary users and professional craftsmen. Many of the elements that make up the solvent are broadly specialized. Various organic products dissolve easily in the composition.

Substance R-5 is a mixture of organic solvents characterized by volatility.

These are components such as:

• acetone;
• esters;
• toluene;
• butyl acetate;
• ketone.

The solvent can have a colorless texture or a slight yellowish tint. A high-quality composition should not have visible suspended particles. The mass is homogeneous in texture, which allows it to be applied evenly and accurately.

Manufacturing companies provide a savings period for a year from the date of production. After opening the sealed package, the solution in the container must be stored in a shaded or dark place away from children and animals. Be sure to close the container lid tightly.... The room should be kept at a low temperature.

This type of solvent can only be used in special rooms that are adapted for such formulations, for example, in industrial workshops or workshops.

You can apply the composition in rooms in which:

• there is a full-fledged exhaust ventilation operating at full strength;
• a fire safety system has been installed;
• there is protection for electrical cables and other equipment.

Let's note the physical and chemical properties:

• The permissible presence of an aqueous impurity in the solution should not exceed 0.7%.
• Particle volatility (diethyl ether) can vary from 9 to 15 units.
• The minimum ignition temperature limit of a liquid is -12 degrees Celsius.
• The density of the solvent is between 0.82 and 0.85 g / cm3 (assuming the room temperature is about 20 degrees above zero).
• The coagulation index is about 30%.
• The maximum acid number is not more than 0.07 mg KOH / g.

The solvent has a strong and unpleasant odor that quickly spreads to the room. The compositions obtained such properties due to volatile compounds in solution. The solvent contains 40% toluene, as well as about 30% butyl acetate and acetone known to all.The first component is aggressive and active.

Excellent ventilation and thorough ventilation are essential when working with the substance.

First of all, this type of composition is used to dilute paints and varnishes. R-5 grade solvent is used together with solutions based on PSH LP and PSH-LS resins. The consumable interacts remarkably with other compounds with organosilicon, polyacrylic, epoxy resins, rubber and other elements that form a film on the surface. When working with varnishes and paints (enamel), an effective composition is added in small portions, carefully following the changes in the state of the paintwork.

It is necessary to pour in the solvent carefully, constantly stirring the main composition until you achieve the desired result. Despite the fact that the substance has a wide scope of use, it cannot be called universal. In certain cases, professionals strongly recommend that you completely abandon it in favor of a different composition. Given the huge selection of products, it will not be difficult to find the right product.

Composition R-5 can be used for cleaning already painted surfaces or equipment and tools.that were used for staining. The composition will help remove particles of varnish and paint. Special components easily dissolve a variety of organic compounds, removing even old and stubborn traces.

If we are talking about carrying out large-scale painting (decoration), then you cannot do without an effective tool. In this case, large batches of solution are purchased.

Before you start working with a solvent, you need to get adequate preparation and protect yourself from harmful vapors. Remember that the individual components that make up the composition can negatively affect your well-being and health. Hydrocarbons, ketones, as well as other compounds and components cause the development of skin diseases, headaches, allergic reactions and discharges of varying severity. Volatile elements, which cause harmful vapors, affect the mucous membrane of the eyes as well as the respiratory tract. Sometimes, when using these formulations, nausea is noted.

Considering all of the above, it is worth taking care of reducing the negative effect. Special work clothing and accessories are needed not only to protect the hands, but also the face, eyes and nose. You will definitely need special goggles, a respirator mask and gloves... Since the composition is flammable, refrain from smoking and using open flames during work.

Solvents are also used if necessary to quickly and effectively degrease the surface. Composition R-5 is also suitable for these purposes. Even a small amount will be sufficient to remove grease and oil stains from the substrate. No calculation is required for standard cleaning. It is enough to moisten a rag with the composition and carefully treat the surface. Do not pour solvent on the surface: aggressive components of the composition can cause irreparable harm to it..

After treatment with solvent, it is necessary to remove its remnants with a dry cloth made of thick paper or cloth. Evaluate the result: if greasy stains remain, repeat the cleaning procedureI am. However, given the effectiveness of this brand of solvent, one wipe is sufficient. Do not rub the solvent into the base so as not to ruin it... There are certain conditions under which it is desirable to carry out the degreasing process.

Thinner R-5 is an effective, efficient agent that is used not only for diluting paints and varnishes, but also for cleaning surfaces and tools. It is necessary to work with the substance carefully so as not to damage the treated surface.
